SPECIFICATION forming part of Letters Patent No. 554,663, dated February 18, 1896.

A li ati filed December 29, 1894- Serial No. 533,235. (No model.) I

To all whom it may concern:

Be it known that 1, WILLIAM E. DUNCAN, a citizen of the United States, residing at Southington, in the county of Hartford and State of- Connecticut, have invented certain new and useful Improvements in Meat-Cutters, of which the following is a specification.

My invention relates to improvements in meat-cutters, and the chief object of my improvement is to so form the delivery end of the case and. rotary cutter and forcer that they may be cast in the proper form without coring, whereby they are not only more cheaply produced but can be given a more efficient form.

In the accompanying drawings, Figure 1 is aperspective view of my meat-cutter. Fig. 2 is a central longitudinal section of the case. Fig. 3 is a detached elevation of the delivery end of the case lookin g squarely into said end. Fig. A is a side elevation of the combined rotary forcer and cutter, the two parts thereof being represented as somewhat separated in order to better show that they are separately constructed; and Fig. 5 is an axial section of the delivery end of the combined rotary forcer and cutter.

The body A or main portion of the case may be of the ordinary form, the same being mainly cylindrical with the hopper B near one end, and the bearing 6 for the shaft 7 of the combined forcer and cutter at said end, while the interior is provided with feedingribs 8. If these ribs are combined with a closely-fitting rotary forcer they will cut as well as feed; but it is not necessary to my improvement that they shall be thus closely fitted. This portion of the case can be made in the ordinary manner-that is, by casting on a core.

In order that the delivery end C of the case may be cast without coring and at the same time be given an efficient form, I make it separately from the case and provide the confronting faces of the parts A C with flanges 9, in which screws, as at 10, may be secured for holding said parts together. In lieu of the flanges and screws other known means of securing two parts together may be employedas,for example, providing said parts with concentric male and female screw-threaded portions and screwing them together. This delivery end is made to taper or flare outwardly, the inner diameter at its smallest end corre sponding substantially with the inner diameter of the body A of the case: Upon its inside I form cutting-ribs 11, which preferably extend somewhat obliquely to the length of the case and are also made hooked or overhanging on that side toward which the peripheral port-ion of the combined forcer and cutter moves when in the act of cutting. In order to cast this part without coring it is essential that the inner ribbed surface shall be shaped specially for an endwise draft in molding.

The mouth or larger end of the part C has on its inner side a bearing 12 for the rim 13 of the combinedforcer and cutter D E. An inclined face 14 extends from the bearing 12 to the inner edge of the cutting-ribs 11, meeting said ribs at an angle, whereby the ends of said ribs terminate at said face. I have shown every alternate cutting-rib 11 with its edge at the inner end partly cut away, making said cut-away ribs in effect slightly shorter than the others; but this is not material. It

is only desirable when one of the ribs terminates midway between two of the feedingribs 8, the cutting away avoiding an abrupt shoulder at that point. When a cutting-rib extends directly from in front of a feedingrib the abrupt shoulder is substantially covered by said feeding-rib.

The forcer or part D of the combined forcer and cutter is or may be of the ordinary form. The delivery end or head E flares outwardly, terminating in the rim 13. Its periphery is provided with cutting-ribs 15,- the longer portions of which are fitted to the longitudinal edges of the cutting-ribs 11 of the case, while their shorter edges are fitted to the ends of said ribs of the case where they run out at the inclined face 14. A space is left under the rim 13 between each two adjoining ribs, as best shown in Fig. 1, and each of the cutting-ribs 15 is preferably inclined with reference to the length of said combined forcer and cutter. In order to save stock, I form the delivery end E hollow, as shown, and in order to enable it to be cast by drawing the pattern endwise from the mold without coring, I form said end E separately from the forcer or part D and subsequently secure them together by any proper means-as, for example, with a screw 16 extended through said end into the end of the part D-while the dowel-pins 17 in one part, entering proper sockets or holes in the outer part, insure the part E from independent rotation.

The part D can be readily cast without coring by drawing the pattern sidewise from the mold,-as with the ordinary forcer. In order to hold the cutting-ribs of the case and combined forcer and cutter in engagement it is necessary that said combined forcer and cutter be secured against moving endwise. Any ordinary devices may be employed for this purpose-as, for example, letting the hub 18 of the crank 19 abut against the end of the bearing (3 and holding it in place by a collar 20 and adj Listing-screw 21, the same being a well-known construction in meat'cutters.

In use the cylindrical portion of the case and combined foreer and cutter will draw in the meat and force it along toward the delivery end, where it will enter the spaces between the cutting-ribs and be cut, as said ribs ass one over the other with a shearin cut.

The meat will be partly cut by the longitudinal portion of the ribs 11 011 the case and engaging portions of the moving cutting-ribs 15, while the final cut is made by the ends of the ribs 11 and engaging portions of the ribs 15. The space between the ribs and under the rim 13 leave a free and unobstructed delivery of the reduced meat in the lines of the cutting and forcing blades.

The cutter can be cheaply formed, is of a compact form, of light weight, and is very efficient in operation.

I claim as my invention- 1. A meat-cutter comprising a case and combined forcer'and cutter, said combined forcer and cutter having a spirally-ribbed and substantially cylindrical. forcer portion, and a separately-constructed peripherallyribbed and outwardly-flaring cutter portion at the delivery end, with its ribs extending substantially in the longitudinal direction of said combined forcer and cutter and at angle to the said cylindrical portion thereof, substantially as described and for the purpose specified.

2. A meat-cutter case having at the delivery end the outwardly-flaring portion provided with internal and longitudinal cutting-ribs the cutting-edges of which extend along their length and across their ends, in combination with a combined forcer and cutter having continuous cutting ribs with one portion fitted to and acting against the longitudinally-extended cutting-edges of the ribs of the case, and another portion of the same ribs fitted to and acting against the end cutting-edges of the same ribs of the case, substantially as described and for the purpose specified.

3. A meat-cutter having a combined forcer and cutter with the outwardly-flarin g delivery end of said combined forcer and cutter provided with the outer rim 13, and substantially longitudinal ribs that extend continuously through the space inclosed by said rim, substantially as described and for the purpose specified.

l. A meat-cutter having at the delivery end of its rotary member a conical body portion or core, and substantially longitudinal ribs projecting radially from said body portion, and a rim 13 connecting the outer ortop edges of said ribs at their ends, substantially as described and for the purpose specified.

5. A meat-cutter having at the delivery end of its rotary member a series of radially-pie jecting ribs, and an outer rim the inner diameter of which rim is fully equal to the greatest cutting diameter as formed by said ribs, substantially as described and for the purpose specified.
